Transport and Magnetism in Topological Semimetals

Topological Semimetals host unusual bulk and surface electronic modes intertwined with the magnetic and crystallographic symmetries of the host crystal. Bulk electrical transport measurements have proven to be incisive probes of the emergent properties of these states. Here we focus on the role of symmetry to control such behavior in terms of Berry curvature driven Hall effects. In both rare earth and transition element containing systems these robust effects allow for a direct probe of the exotic states near the Fermi level. We discuss prospects for designing systems with further enhanced responses via symmetry considerations.
